FREDRICKP. ROSBAOK, OF SPRINGFIELD, MISSOURI.

GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 247,693, dated September 27, 1881.

* Application filed January 27, 1881. (Model) To all whom t'tmay concern Be it known that I, FREDRICK PETER Ros- BAOK, of Springfield, in the county of Greene and State of Missouri, have invented a new and useful Improvement in Binders for Harvesters, of which the following is a specification.

Figure l is a plan view of my improvement. Fig. 2 is an elevation of one side of the same. Fig. 3 is an elevation of the other side of the same, the platform being shown in section. Fig. 4 is a sectional elevation taken through the line :r at, Fig. 3. Fig. 5 is a sectional plan view of a part of the same taken through the line 3 Fig. 4. Fig.6 is a sectional plan view of a part of ihe sarne taken through the line z z, Fig. 4. Fig. 7 is a side elevation of a part of the knot-tying mechanism. Figs. 8, 9, 10, 11, 12 are views of parts of the knot-tying mechanism.

Similar letters of reference indicate corresponding parts.

The object of this invention is to facilitate the removal of cut grain from a harvesterplatform and the binding of the grain into bundles.

The invention consists in providing the platform of a harvester with a hollow-journal havin g. a cavity of sufficient size to receive a gavel, a supporting drive-wheel revolving upon' the hollow journal and carrying the tying mechanism, and curved contracting flan gcs to guide the grain end foremost into the cavity of the said hollow journal; and, also, in the combination, with the wheel and hollow journal, of a mechanism for carrying the cord around the gavel and holding the ends of the cord while the gavel is being tied, a mechanism for forming the knot'loop, a mechanism for slipping the loop upon the cord and drawing the knot tight, and a mechanism for cutting 01% the ends of the cord, all constructed and operating as will be hereinafter fully described.

A represents the platform of an ordinary harvester, which is extended at the side, and has curved flanges or guides B attached to it, to guide the grain to the inner side of the rear part of the said platform and into the cavity of the hollow journal 0, so as to discharge the grain at the side of the driving mechanism and out of the way of the machine in its next round. The curvedflanges B gradually approach each other, as shown in Fig. 1, so as to contract the grain into a gavel as it is bein g moved back upon the platform and cause it to enter endwise into the interior of the hollow or ring journal 0, which is secured at its forward side to the inner rear part of the platform A by connecting-plate D or other suitable means, and at its rear side by a plate, D, which slides in a flanged plate or keeper, D attached to the platform A, to give the wheel '11 a little play to prevent it from binding when the machine is being turned.

The gavel is guided into the interior of the hollowjournal G by an apron, E, attached to the platform A, and its outer end is supported by an apron, F, placed at the other side of the said journal, and connected with the said platform by arms or brackets G. The cavity of the hollow journal 0 is made of such a size as to receive a loose gavel without cramping or compressing the stalks.

Upon the journal 0 is placed. a wheel, H, which is revolved by contact with the ground, and is kept inplace upon the said journal by flanges 1, one of the said flanges being formed upon and the other attached to the said journal C.

With the inner side of the wheel H is connected by studs J a rack-bar, K, which is curved in the arc of a circle concentric with the said wheel H, and the teeth of which at each revolution of the wheel H engage with the teeth of the gear-wheel L, which operates the rake mechanism. At each revolution of the wheel H the rake-head T is carried forward over the platform A and then back, sweeping the grain into the interior of the hollo'wjournal C.

To the plate or bracket D, that connects the rear part of the hollow journal 0 with the platform A, is attached a plate, b, which projects at the outer side of the rear part of the wheel H, and has a hole formed through it for the passage of the tying-cord 0, so that the cord will pass to the wheel H in such a position that the tying mechanism will never fail to take hold of the said cord.

, To the outer side of the wheel H, near its rim, is attached a spring-bar, d, the forward end of which is inclined, as shown in Fig. 5, to allow the separate ends of the cords c to enter and to be pushed back by the entrance of subsequent ends.

7 e is the knot-tyer, which is made curved or cam-shaped, with a slot in its projecting end to receive the cords, and having hooks upon the opposite sides of the said slot to hold the cords, as shown in Figs. 4, 5, 9,10, and 12. The knot-tyer e is formed upon the outer end of a shaft,f, that works in a hole through the wheel H, near its central bearing. The base of the knot-tyer e is flattened upon one side, to rest against the flange of the hollow journal O, to keep the said tyer from turning except at the proper time. The inner end of the shaft f projects and has a pinion, g, which engages with a stationary rack, h, attached to the inner end of the hollowjournal C, to turn the tyer c to wind the cords 0 around the shank of said tyer and form the loop for the knot. The rack h leaves the knot-tyer 0 with its curved back toward the front, so that the loop of the knot can be readily pushed off by the stripper, to be hereinafter described, after which the said tyer is turned through a half-revolution by a short rack, i, supported from the inner end of the hollowjournal C, as shown in Figs. 3 and 6.

j is the finger, which is made with a projecting end to pass alongthe side of the tyer c, and which is recessed to allow the said tyer to turn. The fingerj is formed upon or attached to the end of a square bar, 7;, which slides in a square hole in the central part of the wheel H a little in front of the tyer e. The finger j is moved outward and back by a pin, 1, attached to the bar k, and which enters a cam-groove, m, in the outer surface of the hollow journal 0. The groove mis made with an outward incline to push the finger j outward just before the tyer 0 begins to turn to form the loop, and with an inward incline to draw the finger back as the tyer e completesits revolution. As the finger j moves outward it raises the parts of the cord between the tyer c and the bundle to the outer edge of the cord-guide n, so that the loop will be formed beneath the said parts of the cord, and so that the said parts or the cord can be pinched between the curved edge of the flange upon the said cord-guide n and the edge of the shield o, to prevent the part of the cord that passes around the bundle from being loosened when the cord is cut at the outer side of the knot. The shield 0 also serves to guide the single cord over the tying mechanism when the said cord is being passed around the bundle. As the knot-tyer 0 begins to turn in forming the loop the parts of the cord at the inner side of the said tyer pass between the guide 1) and the wheel H and enter the space between the recessed inner edge of the said guide 1) and the inclined edge of the knife q, which space gradually narrows, so that the cord will be out at the proper time. The knife (1 is attached to the outer part of the stripperr and the guides 11 and n are attached to or formed upon the outer and inner parts of the said stripper r. The parts of the stripper are connected with the outer end of the hollow journal 0, and their adjacent faces gradually approach each other and have inclined shoulders or teeth formed upon them, so that as the tyer 0 passes between them they will strip the loop olf the said tyer, slip the loop back toward the bundle,

and then hold the knot until the hooks of the tyer have drawn the ends of the cord through theloop, forming a knot that cannot slip or be accidentally untied.

In using the machine, the cord 0 from a ball or spool secured to the platformA or some other convenient part of the harvester is passed through the perforation in the guide-plate b, and is secured to the cord-carrier d. As the wheel H revolves the cord slides over the shield 0 and is carried around the gavel, the inner edge of the apron F serving as a guide to keep the cord in place as it is carried around the gavel. As the wheel H completes its revolution the cord-carrier d takes hold of the cord 0 at the inner side of the cord-guide b, so that both ends of the part of the cord that passes around the bundle will be securely held. Both parts of the cord now enter the slot of the tyer e. The finger j moves outward to raise the parts of the cord between the tyer c and the bundle over the outer edge of the guide a, and the tyer 0 turns to form the loop. The flngerj is then drawn back, the cord between the tyer e and the cord-carrier d is cut by the knife q, the loop of cord is stripped off the tyer e, is slipped back toward the bundle by the strippers r, and is held by the said strippers 1' until the ends of the cord have been drawn through the loop by the tyer c. The knot then slips out through a notch in the inner edge of the shield 0, the bundle is dropped from the machine and another gavel is received from the rake, which is bound in turn,and so on, a bundle being bound at each revolution of the wheel H.

The invention concerning the rake forms no part of this application, but will constitute the subject-matter of a new application.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a binder for harvesters, the combination, with the wheel H and hollow journal 0, having guide-groove an, of the fingerj, cordguide n, and knot-tyer e, substantially as and for the purpose herein shown and described.

2. In a binder for harvesters, the combination, with the wheel H and cord-carrier d, of the knife q and recessed guide 19, substantially as and for the purpose herein shown and described.

3. In a binder, the combination, with the wheel H and knot-tyer c, of the toothed strippers 1", whereby the loop is stripped from the tyer and slipped toward the bundle to draw the knot tight, substantially as set forth.

4. In a binder for harvesters, the combination, with the wheel H, the knot'tyer, the cutter, and the hollowjournal O, of the shield 0 and the flanged guide 12., for holding the parts of the cord next the bundle while the ends of the cords are being cut and the knot drawn tight, substantially as set forth.
